Be it known that I, GEORGE SUMMEEs OROTTS, of Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, have invented a newand useful Improvement in Glass-Batch Mixers, of which the following isa full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorrespondingparts of both the figures.

Figure 1, Sheet 1, is a sectional plan view of my improvement, partsbeing broken away; and Fig. 2, Sheet 2, is a sectional side elevation ofthe same with parts broken away.

The object of this invention is to economize time, labor, and expense inpreparing batches for glass-furnaces, and also to promote thoroughnessin the preparation of such batches.

The invention consists in a batch-mixer constructed with a series ofelevators and a box and a discharge-slide and their spouts forintroducing the material into the mixing-cylinder, where it isthoroughly mixed and then discharged upon the screen, so that thematerial will be mixed and screened with one handling, as will behereinafter fully described.

A represents bins to receive the sand, sodaash, and lime, which bins arerepresented in the drawings as standing upon the floor, but which inpractice are designed to be placed in openings in the floor with theirtops flush with the surface of the said floor, so that the materials canbe shoveled from the floor into the said bins without being lifted. Thematerials are taken from the bins A by the buckets B of elevators, theendless belts O of which pass around pulleys D, pivoted within the saidbins, and around pulleys E, attached to the driveshaft F, placed in theupper part of the building. The buckets B are graduated in size, so thatthe proper relative quantities of the materials will be taken from thebins, and the necessity of weighing the said materials will be avoided.The materials are discharged from the buckets B into the spouts G, bywhich they are conducted into the hopper H of the mixing-cylinder I.Into the hopper H is also introduced, through the spout J, salt from thebox or bin K. The salt is removed from the box K and discharged into thespout by a slide, L, which has an aperture, M, formed through UNITEDSTATES PATENT OFFICE.

GLASS-BATCH MIXER.

SPECIFICATION forming part of Letters Patent No. 284,121, dated August28, 1883.

Application filed June 2,1883. (Modem it of such a size as to containthe amount of salt to be added to the other ingredients at a time. Theslide L discharges the salt through an, opening, N, in the bottom of thebox K, beneath the cut-off 0, so that no more salt can be discharged ateach movement of the slid L than the full of the aperture M.

Tothe end of the slide L that projects through an opening in the end ofthe box K is'attached the end of a pitman, P, the other end of which ispivoted to the crank Q, the journals of which revolve in bearingsattached to the frame of the building, and to one of the said journalsis attached a pulley, R. Around the pulley R passes a belt, S, which also lrpasses around a pulley, T, attached to the drive-shaft F. To theother end of the shaft F is attached a fast pulley, U, and a loosepulley, V, to receive the driving-belt. To the shaft F is also attacheda pulley, WV, around which passes a belt, X. The belt X also passesaround a pulley, Y, attached to the shaft Z, which passes through thecylinder I and revolves in bearings attached to the frame of thebuilding or other suitable support.

To the shaft Z, within the cylinder l, are attached a number of radialarms or paddles, 1, by the action of which the materials are thoroughlymixed as they pass through the said cylinder 1. The material isdischarged from the cylinder I into the screen 2, through which the finematerial falls into the batch-carts, by which it is carried to thefurnace. Anylumps that may be in the materials fall from the lower endof the screen 2 into some suitable re ceiver. The upper end of thescreen 2 is pivoted to a post, 3, or other suitable support, and itslower end is supported from the frame of the building by rods 4, asshown in Figs. 1 and 2.

To the side of the lower end of the screen 2 is hinged the end of theconnecting-rod 5, the other end of which is attached to the end of 5 thearm 6, attached to the shaft 7 The shaft 7 is vertical, and revolves inbearings connected with the frame of the building, and to it is attacheda second arm, 8, to the outer end of which is attached the end of aconnecting-rod, I00 9. The other end of the rod 9 is pivoted to acrank-pin or crank, .10, attached to a small gear-wheel, 11, pivoted tothe support for the journal of the cylinder-shaft Z, or to othersuitable support. The teeth of the gear-wheel 11 mesh into the teeth ofthe larger gear-wheel 12, attached to the cylinder-shaft Z, so that thescreen 2 will be vibratedfrom'the said shaft. With this construction thematerials will be delivered into the cylinder I in proper relativequantities, will be thoroughly \mixedwhile passing through the saidcylinder, and will be screened and delivered to the batch-carts with onehandling, so that the time and labor required in preparing the batch,and consequently the cost, will be greatly lessened, while the work willbe more thdroughly done than is possible with hand-mixing.

Having thus fully described my invention, I claim asinew and desire tosecure by Letters Patent; v

1. The combination,with a mixer, of a single hopper, H, inclined spoutsleading thereimo, and suitable means for supplying said spouts with adefinite proportion of each ingredient at their upper ends, whereby theseveral ingredients are brought together in their required proportionsas they enter the mixer.

2. In a batch-mixer, the combination, with the mixing-cylinder I, of theseries of spouts G and graded elevators B O, substantially as hereinshown and described, whereby several materials can be introduced inproper proportions into the same cylinder and mixed, as set forth.

holding the several ingredients to be mixed, of l elevators arranged onthe same shafts, having their respective buckets graduated in size 3 tosuit the proportions required of, the different ingredients and passinginto the said vessels, whereby the buckets of all the elevators movesynchronously and continuously carry up definite proportions of theingredients, as described. p a i 4. In a batch-mixer, the combination,with the'mixing-cylinder I, of the spout J, the box K, and thedischarging-slide L, substantially as herein shown and described,whereby the substance 'in the said box will be introduced into themixing-cylinder at regular intervals and in uniform quantities, as setforth.

5. In a batch-mixer, the combination, with themixing-cylinder- I, of thegraded elevators spouts G J, the screen 2, and a driving mech anism,substantially as herein shown and described, whereby the variousingredients for a batch are mixed and screened at one opera- 55 tion, asset forth.
